Hybrid tea rose plant named &#39;Meitelov&#39;

ABSTRACT

A new and distinct variety of Hybrid Tea rose plant is provided which abundantly forms attractive large double yellow blossoms that are lightly perfumed. The plant exhibits a strong vigorous growth habit, semi-glossy decorative dark green foliage, and excellent disease resistance. The attractive dark green foliage contrasts nicely with the yellow blossoms. The new variety is particularly well suited for growing as attractive ornamentation in the landscape such as in parks and gardens.

BOTANICAL/COMMERCIAL CLASSIFICATION

Rosa hybrida/Hybrid Tea Rose

VARIETAL DENOMINATION

cv. Meitelov

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Hybrid Tea rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) of the new variety was formed by crossing the ‘Meidragelac’ variety (non-patented in the United States) and the ‘Meikinosi’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) was the ‘Korbelma’ variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:

-   -   (‘Meidragelac’×‘Meikinosi’)×‘Korbelma’.

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety It was found that the new variety of Hybrid Tea rose plant of the present invention possesses the following combination of characteristics:

-   -   (a) exhibits an erect growth habit,     -   (b) exhibits a strong vigorous growth habit,     -   (c) abundantly forms over substantially the entire season         attractive large double yellow blossoms that are lightly         perfumed,     -   (d) forms decorative dark green semi-glossy foliage that         contrasts well with the yellow blossoms, and     -   (e) is particularly well suited for growing as attractive         ornamentation in the landscape.

The disease resistance of the new variety is excellent.

The new variety of the present invention can be readily distinguished from its ancestors. More specifically, the ‘Meidragelac’ variety displays a shorter growth habit and bears bicolored salmon flowers, the ‘Meikinosi’ variety displays a shorter growth habit and bears flowers having a lesser number of petals, and the ‘Korbelma’ variety displays dissimilar high-pointed buds and flowers having a lesser number of petals.

The new variety well meets the needs of the horticultural industry and can be grown to advantage in parks and gardens.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and cuttage. Asexual propagation by the above-mentioned techniques in France has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another.

The initiation of rooting on cuttings takes place in an expeditious manner. For instance, when semi-hardwood cuttings are placed in the greenhouse during July, new plants commonly can be planted in the field during the second week of September.

The new variety has been named the ‘Meitelov’ variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety were one year of age and were observed during September while budded on Rosa froebelli understock and growing in outdoors at Le Cannet des Maures, Var, France. Dimensions in centimeters are indicated at the bottom of the photograph.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The description is based on the observation of one year-old plants during October while budded on Rosa froebelli understock and growing outdoors at Le Cannet des Maures, Var, France. The coloration in more common terms precedes reference to the chart in some instances. Such terminology is to be accorded its ordinary dictionary significance.
